D.I.D is the number one motorcycle chain in the world. D.I.D chains are used by factory races teams from all manufacturers in race series everywhere.

Pinning your bike out of every turn might tear apart the stock chain, but D.I.D and their 520NZ chain will not let you, or your race for first, down.

  • For machines originally equipped with non-O-ring chains.
  • Solid rollers.
  • Shot-peened parts.
  • High cylindrical and roundness accuracy.
  • Exacting tolerances provide low friction.
  • DHA pin treatment - hard chromium-carbide layer formed on pin surface for exceptional strength and wear resistance.
  • Pre-stretched.
  • Special alloy steel with extended riveted bushing "anti-kink" design.
  • Highest quality non-O-ring chain in overall combined performance.
  • Up to 19% higher tensile strength; average tensile strength of 8,220 pounds.
  • Wear life index: 410.
  • Rated for up to a 250cc bike.
  • Weight (per 100 links): 3.54 pounds.
  • Includes a clip-style master link.
  • 120 links.
  • Note: Non-sealed chains require more regular maintenance than sealed (O-ring, X-ring) versions and are mainly recommended for off-road use.

D.I.D's exclusive SDH (Super DH) pin treatment is the secret behind the superior performance of the NZ Series chains. This high-tech pin treatment forms an extremely hard chromium carbide layer on the pin's surface while maintaining a soft inner core. SDH treated pins have extreme impact strength while maintaining outstanding shock absorption. This treatment creates a chain with anti-oxidation properties and superior wear resistance against invasion of hard foreign materials.

The chain hasn't stretched much, but it does have a fair amount of side to side play after only a few rides. Seems pretty solid otherwise. Master link was a PITA to install. I literally had to use a round file to make the holes larger so that it would fit together. Probably wouldn't buy another one...

Excellent chain

This is an awesome chain! I have ridden many hours and through the mud and the muck. It is holding up great. Even after many hours of riding, I haven't had to adjust it at all.

DID 520 Heavy Duty Chain - 120 Links

Heavier duty chain, though I have a heavier one on my other bike. Not bad for the price, but I would prefer something a bit more beefier. Definitely not a bad purchase for the money.

Decent CHEAP chain I guess?

I suppose I can't fault the chain cause I was bein cheap. Got the "Heavy Duty" thinking it would last longer than the regulars, but my YZ450F stretches the heck out of it everytime I ride it. Spec is 40-50mm of slack in chain I've gone to setting it just under 40mm and it stretches past 50mm after every ride! My advice is to spend the extra $50 and get a nice o-ring chain if you have a hot 450, would probably last a long time on a stock 250 though. Never had so much trouble getting a master link to snap together, don't know why either?

Yes, you will need to cut it down to fit your specific ATV set up.

Will this chain fit 13tooth front 38 tooth back?
I have a 05 Polaris Predator 500 and I was wondering if a 13t front and a 38t back will work with this length chain. How do I know or how can I tell?

With the stock 14/38 gearing on your bike a 92 link chain is required. This 120 link chain would definitely be long enough to fit with your 13/38 gearing. You need to be cut the chain to the correct length for your bike.

Regarding a '95 xr650L, what is the smallest, strongest chain that supports street only use? I want the widest possible tire for the rear.?

When it comes to chains you have a couple of different options. You are going going to have standard unsealed chains and you will have sealed chains(x-ring or o-ring). The standard chains will be the narrowest chains as they do not need to have the extra width that the seals will require. Standard chains will require more maintenance and more frequent lubing due to the fact that internal rollers are not sealed from the elements and these are not the number one choice for street riding. The sealed chains tend to last longer as the internal rollers are sealed for road grime and dirt. They will require less maintenance as the rollers come pre-lubed and the lube is held in by the seals. They typically weigh more and will rob some horsepower due to the added friction in the chain from the seals. I would determine which style you would like to go with, as within each style, the width does not vary much from chain to chain and from manufacturer to manufacturer.

Yes this chain would be good for your 87 Quadrunner. You may want to look into an o-ring chain though depending on where you ride as they will typically last longer if you are worried about reliability. The o-ring chain costs a little more but will be much better bang for your buck in the long run.

Is this chain better for rm 125 rather than an o-ring chain?
I am running steel sprockets on my 125cc. Will an o-ring cause a lot of drag on 125?

O-ring chains will cause drag compared to a non O-ring chain. It's not enough that you would probably notice it. If you want a chain that will last longer, get the o-ring. If the chain drag isn't something you want, get a non O-ring.
